Title: Improvements in talking machines
IPC: G11B17/16
Filed: 1928-07-19
Abstract: 317,204. Gramophone Co., Ltd., (Victor Talking Machine Co.). July 19, 1928. Mandrels; magazine gramophones.-Means for expanding the end of the turntable spindle within the central aperture of the record to prevent relative rotation during playing, comprise a turntable spindle 5, the tubular end of which has longitudinal slits, the parts between the slits being expanded by a vertically movable member 7. The member 7 is pressed into fixing position by a spring 9 and can be released by fingers 10 operated by hand or automatically in the case of a magazine gramophone in which the turntable carries a pile of records released one at a time from the top of the spindle. In the form shown in Fig. 1, the member 7 has a ball 19 engaging the coned interior of the spindle when the member is moved upwardly. Fig. 2 shows a modification in which expansion of the spindle takes place when the member 7 is moved downwardly.

Title: Improvements relating to the control of laundry washing machines and other machines
Inventor: WOODWARD STANLEY
IPC: H01H43/12
Filed: 1950-08-25
Abstract: 693,045. Stencil switches. BAKER PERKINS, Ltd. Aug. 21, 1951 [Aug. 25, 1950], No. 21112/50. Class 38(v) [Also in Groups VIII and XIX] Means for indicating the various phases of a machine cycle such as the wash and rinse phases of a washing machine cycle comprises a series of lamps (19, 27) or other indicating means arranged' in separate circuits connected to a circuit changing switch which is controlled by a rotary control card 5, the control incorporating contact fingers (9, 12, 23, 15) co-operating with the card and connected to an impulse coil 10 a circuit changing switch arm or arms (13, 24) and a release coil 16 of the circuit changing switch, the coils 10, 16 being energised by the fingers contacting with a contact gauze 1a through slots in the card. Groups 6 and 7 of slots are provided for the wash and rinse phases respectively. The control card shown is wrapped on a control drum 1, but a flat perforated disc may be employed. In operation, as the drum 1 rotates, the finger 12 engages in a slot 11 and the finger 9 in the first of a number of holes 8. The impulse coil 10 is thus energised to move the arm 13 to the first contact 17 and illuminate the lamp 19 in the first wash circuit. The lamps 19 are illuminated in turn until the wash phase is complete whereupon finger 15 enters a hole 14 to energise the release coil 16 and return switch arm 13 to zero. Similar action occurs with the rinse phase lamps 27 and switch arm 24 as the holes 20, 21, 22 of group 7 are engaged by fingers 9, 23, 15. A red lamp may be energised on completion of the washing cycle. Instead of lamps 19, 27, other indicators may be used e.g. a shutter, bell or buzzer.

Alternatively the roller spacing means may be of annular form and may close the opening between the support and the drum.
Patent GB-640383-A (GB)
Title: A process for the production of unsaturated carbonylic compounds
Filed: 1947-08-05
Abstract: Vinyl-type aldehydes and ketones, i.e. compounds containing an olefinic linkage between two carbon atoms of aliphatic character, one of which is directly linked to an aldehyde or ketone group, are obtained by reacting an olefinic hydrocarbon containing at least three carbon atoms in the molecule with oxygen at elevated temperatures in the presence of cuprous oxide, the carbonylic compound having the same number of carbon atoms in the molecule as the olefinic hydrocarbon from which it is derived.  The process may take place with added oxygen or the oxygen may be obtained from the cuprous oxide.  Olefinic hydrocarbons include open chain and cyclic compounds and amongst many specified the following may be instanced: propylene, isobutylene, 4-methyl-pentene-1, cyclopentene and 3-methyl-cyclohexene.  They may be present as mixtures with one another or with paraffins.  The cuprous oxide is preferably supported on or mixed with carriers of conventional type.  Thus cupric nitrate, cupric ammonium nitrate or other copper salt is deposited on a carrier, oxidized to cupric oxide and reduced to cuprous oxide.  The preferred temperature range is 150-450 DEG  C. and steam may be used as a temperature control.  The catalyst may be fluidized although fixed bed catalysts are preferred.  The carbonyl compounds may be obtained from the reaction products by scrubbing with a solvent, e.g. cold water with a wetting agent, followed by distillation.  In examples: (1) propylene; (3) b -and (4) a -butylene together with oxygen and steam is passed over cuprous oxide on silicon carbide at 368 DEG  and 355 DEG  C., 310 DEG  C. and 300-330 DEG  C. respectively to give (1) acrolein, (3) and (4) methyl vinyl ketone and in (2) propylene, oxygen and steam are passed through cupric oxide on powdered pumice, the catalyst being agitated, at 375 DEG C., until reduced to cuprous oxide, and then at 325 DEG  C. to give acrolein.

IPC: G11C7/02
Filed: 1964-05-22
Abstract: Ferrite cores-and indeed complete memory arrays-are provided with a plastics coating to reduce magnetostrictive ringing, the coating comprising the uncured residue obtained by evaporating the solvent from a solution containing 2,21-bis(hydroxyphenyl propane)-epichlorohydrin polymer and chlorinated biphenyl.  The polymer has a molecular weight of 900-6,500 and an epoxide equivalent of 400-3,800.  Chlorinated biphenyls up to pentachlorobiphenyl may be used.  Suitable solvents are methyl ethyl ketone and benzene, toluene and ketone mixtures.  The dry coating comprises 80-97% by weight of polymer, and the solution contains 10-42% by weight of solids.  The ratio of polymer to chlorinated biphenyl is preferably 5 : 1.  In manufacture the cores or arrays are dipped into or sprayed with the solution and dried in an evacuated oven at 50  DEG C. for 25 minutes or in air at 50  DEG C. for 60 minutes.  To ensure an uncured state an anti-oxidant, e.g. "Agorite powder" (phenyl betanaphthylamine and hydroquinone monobenzyl ether) may be incorporated.
